Description

Technical Field

[0001] This utility model relates to the field of broadcasting engineering technology, specifically to a cable connector used in broadcasting engineering. Background Technology

[0002] Radio broadcasting is an indispensable way to access information in daily life, and the development of the radio industry is also known as radio engineering. Currently, the construction of radio engineering projects generally focuses on expanding radio coverage to increase its reach. During radio and television broadcasting, a large amount of engineering cables are required, necessitating the connection of these cables. Therefore, engineering cable connection devices used for radio and television coverage are an important type of cable accessory.

[0003] The utility model patent with authorization announcement number CN 220440363 U discloses an engineering cable connection device for broadcast television coverage, including a junction box and a junction cover. A connecting mechanism is symmetrically fixedly connected to the outside of the junction box. The junction box is fixedly installed via the connecting mechanism and the junction cover. A sealing mechanism is fixedly installed at the upper end of the junction box. A waterproof mechanism is symmetrically fixedly installed on the outside of the junction box, and a waterproof component is fixedly installed on the outside of the waterproof mechanism. This utility model adopts the above structure. The first connecting block on the cover and the second connecting block on the junction box can be easily positioned and installed via a square block with screw grooves. Based on the sealed installation of the cover and the junction box, a sealing element with an extended edge is inserted into the upper end of the junction box. Simultaneously, the upper end of the sealing element is inserted into the cover, thereby conveniently providing a sealing protection between the cover and the junction box, thus preventing short circuits caused by water or dust entering the junction box.

[0004] In the aforementioned publicly available results, the structure of fixing the cable using junction boxes and connecting waterproof components lacks a rubber tube structure for fixing the tube connection. This not only makes it difficult to position the cable terminals separately, making separate positioning installation impossible and prone to mutual interference, but also fails to completely adhere to the cable surface for isolation and protection, resulting in poor waterproofing performance, which needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cable connector for broadcasting engineering, which solves the problems of existing connectors being unable to be installed and positioned separately and having poor isolation and waterproofing effects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable connector for broadcasting engineering, comprising a fixed cylinder, a combined ring fixedly connected to one end of the fixed cylinder, a connecting hole provided at the other end of the fixed cylinder, a supporting rubber cylinder fixedly connected inside the connecting hole, an elastic rubber cylinder fixedly laminated to the outer surface of the supporting rubber cylinder, a contraction opening provided at one end of the elastic rubber cylinder, pull rings fixedly connected to both sides of the contraction opening, the pull rings symmetrically connected to both sides of the elastic rubber cylinder, a positioning ring fixedly connected to the other end of the supporting rubber cylinder, an annular skeleton fixedly embedded inside the positioning ring, an annular protrusion fixedly connected inside the supporting rubber cylinder, a positioning groove provided on the end face of the combined ring, and a sealing ring fixedly engaged inside the positioning groove.

[0008] Preferably, the annular protrusion has three layers, which are evenly spaced to support the inner surface of the rubber cylinder.

[0009] Preferably, the elastic rubber cylinder is made of flexible rubber, and its wall thickness is one-third of that of the supporting rubber cylinder. With three layers of evenly distributed annular protrusions, it can be snapped onto the cable surface for support and positioning, ensuring the stability and strength of the connection and facilitating installation and use.

[0010] Preferably, the surface of the combination ring is provided with a combination hole, and a combination screw is inserted into the interior of the combination hole.

[0011] Preferably, one end of the combined screw is connected to a connecting plate, and both ends of the connecting plate are provided with socket holes.

[0012] Preferably, the socket is fitted onto one end surface of the combination screw, and the connecting plate is mounted on one side surface of the combination ring. The combination screw and the connecting plate are connected through the combination hole provided in the combination ring, which allows for separate installation and fixation. This facilitates the enclosed protection of two fixed cylinders positioned on the street, ensuring safety and stability. Furthermore, adjacent positions can be combined to form an integral structure, which is conducive to integrated positioning, has high adaptability, and is convenient for wiring.

[0013] Compared with the prior art, this utility model provides a cable connector for broadcasting engineering, which has the following advantages: Through its design, this cable connector uses a fixed sleeve to support the rubber sleeve and an elastic rubber sleeve, which facilitates separate fitting to the cable joint position, ensuring stability and allowing for complete sealing and protection of the cable surface.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: a cable connector for broadcasting engineering. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4The system includes a fixed cylinder 1, which can be fitted onto the cable connector to form a support and positioning structure for easy connection and protection. One end of the fixed cylinder 1 is fixedly connected to a combination ring 11, and the other end has a connection hole 12. A support rubber cylinder 13 is fixedly connected inside the connection hole 12. An elastic rubber cylinder 14 is fixedly laminated to the outer surface of the support rubber cylinder 13. One end of the elastic rubber cylinder 14 has a contraction opening 15, and pull rings 16 are fixedly connected to both sides of the contraction opening 15. Pulling the pull rings 16 expands the contraction opening 15, allowing it to be fitted onto the cable connector for easy separate installation and positioning. The elastic structure allows for elastic contraction, thus binding the cable surface for a secure and sealed fit, effectively improving waterproofing and ensuring safety and stability. The cable connector, after passing through the elastic rubber cylinder 14, can be inserted into the support rubber cylinder 13 and engaged with the internal annular protrusion 19 for positioning, forming a multi-layered structure. The sealed isolation layer provides high safety and stability. The cable connector emerges from inside the fixed cylinder 1, facilitating the connection and positioning of two cable connectors without interference. This allows for convenient combination installation for protection. Pull rings 16 are symmetrically connected to both sides of the elastic rubber cylinder 14. A positioning ring 17 is fixedly connected to the other end of the supporting rubber cylinder 13. An annular skeleton 18 is fixedly embedded inside the positioning ring 17. An annular protrusion 19 is fixedly connected inside the supporting rubber cylinder 13. A positioning groove 2 is provided on the end face of the combination ring 11, and a sealing ring 21 is fixedly engaged inside the positioning groove 2, allowing for secure and stable installation. This method of installing the supporting rubber cylinder and elastic rubber cylinder through the fixed cylinder facilitates separate fitting to the cable connector position, ensuring stability and a complete seal against the cable surface. The ends can be spliced ​​for improved waterproofing, facilitating positioning and application, and offering high adaptability.

[0018] Please see Figure 2 and Figure 3 The supporting rubber cylinder 13 and the annular protrusion 19 are made of hard rubber and are an integral structure. The annular protrusion 19 has three layers and is evenly distributed on the inner surface of the supporting rubber cylinder 13. The elastic rubber cylinder 14 is made of flexible rubber and its wall thickness is one-third of the wall thickness of the supporting rubber cylinder 13. By evenly distributing the three layers of annular protrusions, it can be snapped onto the cable surface for support and positioning, ensuring the stability and strength of the connection and facilitating installation and use.

[0019] Please see Figure 1 , Figure 2 and Figure 5The surface of the combination ring 11 is provided with a combination hole 22, and a combination screw 23 is inserted into the combination hole 22. One end of the combination screw 23 is connected to a connecting plate 24. Both ends of the connecting plate 24 are provided with sleeve holes 25, which are fitted onto one end of the combination screw 23. The connecting plate 24 is assembled and installed on one side surface of the combination ring 11. The combination screw and the connecting plate are connected through the combination hole of the combination ring, which can be installed and fixed separately. This is conducive to the enclosed protection of two fixed cylinders facing the street, which is safe and stable. Adjacent positions can be combined to form an integral structure, which is conducive to integrated positioning, has high adaptability, and is convenient for wiring. After the fixing cylinder 1 is fitted onto the surface of the cable joint, the cables are connected and positioned. Then, two fixing cylinders 1 can be spliced ​​together. After aligning the combination ring 11, the combination screw 23 is installed, and the threaded nut is tightened for fixation. The sealing ring 21 on the pressing end face of the combination ring 11 is used for sealing and positioning to ensure safety and stability. It can isolate and protect the cable joint position. When connecting, the connecting plate 24 can be assembled and installed on a combination bolt 23 first. This allows the fixing cylinders 1 on adjacent cables to be combined for neat arrangement. It is convenient for multiple groups of cables to be connected into an integrated structure for installation and fixation. It has high adaptability and is convenient for positioning and use.
